Use -Wno-undef to compile jsoncpp.

This should fix this error:
In file included from ../../api/audio/echo_canceller3_config_json.cc:19:
In file included from ../..\rtc_base/strings/json.h:18:
In file included from ../../third_party/jsoncpp/source/include\json/json.h:9:
In file included from ../../third_party/jsoncpp/source/include\json/autolink.h:9:
../../third_party/jsoncpp/source/include\json/config.h(126,5): error: '__GNUC__' is not defined, evaluates to 0 [-Werror,-Wundef]

Maybe we could also fix it upstream.
